Researcher

My primary research interest lies in the investigating methods of knowledge discovery, management, and exchange in content-based retrieval systems for large-scale biomedical media. In this area, I focus on providing researchers and experts with computer-based methods to:

• acquire knowledge from different sources,
• encode tacit knowledge into individual expertise settings,
• make computer-generated knowledge available for peers’ reference.

With the latest advances in science and technology, research projects need to address problems that cross the boundaries of traditional research disciplines. Over the past years I worked with collaborators from other domains and I have successfully applied my research methods to medical informatics for studying patterns of pulmonary diseases found in high-resolution computed tomography images; agronomy for modeling the phenotype-genotype correlations of maize mutants; and geospatial intelligence for discovering relevant knowledge from satellite images. In this context, my research interests are grounded in the need to reduce the semantic gap between human and computer models of representing visual patterns and to develop a knowledge framework that is close to how experts reason when they make decisions.
